' Be itknovvnthatl, CARL W. SwENsoN,

a citizen of the United States, residing at Providence, in the county of Providence and Stateof Rhode Island, have invented certain new and useful Improvements in Headi11g-Machines,of which the following is a SpBClfiCa tiOILwfK 1 My invention relates to a machine adapted to form the head portionof the movable member of a ball and socket fastener;v

The essential objects of my invention are to insure speed of production, and accuracy of shape in the product; to provide adequate feeding and discharging means;'to prevent cramping of the blank during its passage throughthe forming tools; and to prevent A clogging ofthe blanks as they are fed to the forming. tools. i

To the above ends essentially my invention f consists in such parts and combinations of partsas fall within pended claims.

In the accompanying drawings which form apart of this specification.

..Figures 1 and 2, are side and plan elevations respectively of a machine embodying my invention, parts being broken awayto more clearly show operative parts, i Fig. 3, a section on line 8-3 of Fig. 12, Fig. 4:, a fragmentary elevation of the lower; front portion of the hopper wall, Fig. 5,-a transverseisection, partially diagrammatic, of a portion ofthe hopper wall and ofthe adjacent forming mechanism on the scope of the apline 5- 5 of Fig. 4, showingin broken lines various blank,

ports and 16 respectively, anda table or base plate 17 upon the supports. Journaled in the forward portions of the plates 14 and 17 is a driving shaft 19, and in the rear thereof a driven shaft 20; The former is driven by a pul-leyi2l through a belt 22 from any convenient source of power, and a gear 23 on the shaft 19 meshes with a gear 24: on the shaft 20. The forward portion 25 of the plate or table 17 is substantially circular, and hasupon its upper face a marginal annular shoulder 27 to Whoseupper surface is fixed by screws28. or otherwise an ar cuate plate or. die 29 projecting, inwardly from the shoulder and provided upon its inner margin'withan annular bevel portion '30. Its periphery is provided with a curved groove 31 forming two annularresultant projecting. upper and lower portions or shoulders 33. and 34 respectively, the latter projecting more than the former. The shoulder 34 is provided with minute teeth 35 orhasitssurface otherwise roughened, as shown in Fig. 5. Cooperating withthe plate 29 is a. rotary member, represented in a'general way by the reference numeral 37 comprising a disk. 38 fixed to shaft 19 extending below the member; 29 and spaced therefrom, and upon whose central portion is aspacing shoulder 89., Therotary memher is completed by a circular plate or die 10 of less diameterthan. the disk 38,;and having its lower face in the horizontal plane of the lower face of the plate 29: Its upper face has a marginal bevel all. The portions 38 and 40 of the member 37 may, if desired, be integral with each other,jit being necessary in either ,case that the space or marginal recess 43 between the members; be present. The plate10 may be fixed tothe disk 38 or to the shaft 19 in any preferred manner. The peripheryrof the die 40 has an annular groovev 4:7 forming resultant upper and lower shouldersS and 49, the latter eXtending the greater distance. The shoulder 49 has minute teeth 50 or asurface otherwise roughened throughout its periphery. The shoulders 38 and 34 are respectively opposite and in the horizontal planes of: the shoulders 48 and 49. Thus is formed a guideway'or spacebetween the dies 29 and 40 represented in a general way by the reference numeral 51 with a restricted passage 52 formed by the 'lowerpair of shoulders, as shown in Fig. 6, andanenlarged transeccentric to the-die 29 so that the guideway is of gradually diminishing-Widthfrom the entrance thereof to an intermediate point. This difference in width is illustrated of the portion 25 is also-circular and of.

greater diameter and is provided with vertical lugs 58 having, holes '59 to admitscrews 60 to engagev and rigidly maintain acircular wall 61 elevated above the table, which wall constitutes: the side of'a hopper. A disk 62 fastto thesshaft 20 rotates in sliding-contact. with. the bottomedge of-this walLand constitutes the-fioorof theshoppen This disk .has' its periphery in contact withithe periphery of the part 88 of'therdie 37, and its upper face is in the plane of the upper. face of said; part.- The wall 61 abuts against the plate.29. at'itheiend' of the latter: where the entrancet55, occurs, and is provided'in its lowerredgeziwith'a' long areuate shallow slot 61% from which extends a deep slot 65. At one side'ofrtheslot 65 the wall 61' has its surface inclined, as at 66, as shown in Fig. 5, forming a pointed projection 67. The wall6lat the opposite side of the slot is cut awayto form a: tapering surface 68' or reduced wall" portion.

Removably fixed to the' shaft 20 is a hub 7 O having radial arms 71 integral with a cylindrical wall or open drum 72, of slightly less'diameter than the wall'61', and which constitutes a: rotary spacing or selecting member; It has gear teeth 73' upon its periphery. The'lower edge of this member is adjacentor in contact with the face of the disk 62,: and isprovided' with a series of spaced marginal reversed T shaped openings 74 each comprisinga shallowyportion 75, and a deep central portion 7 6; The side walls of the openings 74' are transversely inclined, asshownin Fig. 9, and the portions of the wall adjacent the'opposite sides of the openings are of diife'rent degrees of thickness, forming the projection 78 and the guidesurfacer79. The described parts are fonfeedingr the blanks to the forming, dies. Agearfl 9 fast on the shaft 19 meshing with therteetlr 7 3: drives the drum 72 preferably at a less speed than the=rotation of the diskr62.v g i I i The. means'for discharging-"the formed blanks comprises an a-rcuate attaching strip 80 fixedx'by screws 815 to. the top of the die 29and carrying an. upright curved wall or fiange'i82: integral with a downwardly in cllnedtube 84.. Fi xed to the'shoulder 27by screws is guide-plate 86' extending-into thescavity43;"somecdistance at a poi-ntwithin or. adj 'acent" them'outh of the tube 84:;

The; operation: of. the machine is; as fol- J lowsz; The blanks; are 1 introduced in quantities into the hopper. Each blank, as shown in Fig. 10, comprises the flange or bases? and a-hollow'post 8S "Bythe centrifugal force' ofthe disk 62, the blanks are driven radially until their bases respectively enter the slots 64, 65, and advance into contact with the point 67 and are induced along the inclined face 66 into the guideway 51, as shown in Fig. The flange of each blank slides into the recess 43 of the die 37 and beneath the die 29." The rotating die, engaging the post of the blank, impelsthe blank along the guideway as well asimparting rotary mevementfl thereto. These move ments are facilitated by the marginal teeth 35-and i50. As the blank advances from the broad to the narrow perti ons of the guideway, the dies continuously gradually compress andishape the: post of the blank into the rounded or' spherical head 8'9 shown in Fig. 11: The shoulders at, 4:9' and grooves 31; 47, assist 'togimpart this-final form: During the travel of the' blanle, its flange-finally eontactswith-the plate-on projoction 86 whereby. the blank is-disengaged from the dies-or runway and falls through the tube Set: The b lanksmove throughthe guideway successively and in"= contact with each other insuring speed, quantity-of produetion, and accuracy of form.

The long'slot 6% in the wall 61'aifords means for slidably engaging and guiding a row of blanks through the opening 65", but in order to prevent. choking theformerslot by overlapping flanges dueto' an excessive massing of blanks, the' rotary selective membel' is:' advantageously employed, The spaced openings 'TaHthe-rein :permit passage therethrough; of only a: lim-itedinumber of blanks.- Theseare selectively induced through theopenings-by the disk 62, rotating at" greaterspeed than the; member 72, and are assisted'by the shape --of*the latter adjacent the opening:

@ther modes of applying the principles of my invention" may be employed instead of the one explained, change being=inacle as regards the mechanism herein d1solosed, rovidedthe" means stated by any of the-following claims or the equivalent of such stated means be employed.
